Abstract
A method for reducing shock during a flow of fluid between a higher pressure vessel and a lower pressure vessel. The method includes the steps of providing a conduit between the higher pressure vessel and the lower pressure vessel, and minimizing a rate of pressure change within the second vessel caused by the flow of fluid along the conduit from the higher pressure vessel. The minimizing step includes controlling a rate of flow of fluid between the first vessel and the second vessel over a predetermined duration.
Claims44
A method for reducing shock during a flow of fluid between a first vessel and a second vessel, the method comprising the steps of:
- providing a conduit between the first vessel and the second vessel;
- and
- minimizing a rate of pressure change within the second vessel caused by the flow of fluid along the conduit from the first vessel,
- wherein the minimizing step includes controlling a rate of flow of fluid between the first vessel and the second vessel over a predetermined duration.
A method for controlling a flow of a gas, comprising the steps of:
- directing the gas from a first vessel to a second vessel;
- and
- obtaining a predetermined flow rate profile in the flow between the first and second vessels,
- wherein the obtaining step includes introducing a first pulse into the flow by opening and closing a first valve in an alternating manner.
A method for controlling a flow of a gas, comprising the steps of:
- directing the gas from a first vessel to a second vessel;
- and
- obtaining a predetermined flow rate profile in the flow between the first and second vessels,
- wherein the obtaining step includes providing a flow restrictor in the flow between the first and second vessels, the flow restrictor exhibiting a linear relationship between flow rate and pressure differential.
A gas treatment assembly, comprising:
- first and second vessels each including gas treatment material;
- a manifold connecting the first and second vessels to provide communication of a gas between the first and second vessels;
- and
- a first manifold assembly provided between the first vessel and the manifold, the manifold assembly including:
- a first piston valve, and
- a first porous flow restrictor.
A gas treatment assembly, comprising:
- first and second vessels;
- a manifold connecting the first and second vessels to provide communication of a gas between the first and second vessels;
- and
- first means for minimizing a rate of pressure change within the second vessel caused by a gas flow along the manifold from the first vessel,
- wherein the first minimizing means controls a rate of gas flow between the first vessel and the second vessel over a predetermined duration.
